How to unlock a new glovebox
 

So my glovebox door handle was broken and I ordered a new glovebox (although it is used one) from ebay. When I used my key to lock the new glovebox, it indeed locked but the key cannot unlock the glovebox! Now I know I made a stupid mistake. So how can I unlock the new glovebox. The only way is to contact the seller to mail the key for that glovebox? Thanks very much!
